Description

本発明は、少なくとも部分的に構造化された板金層を巻回して、積層してあるいは絡み合わせて構成され、少なくとも一部の範囲がろう付けされている、特に自動車の排気ガス触媒用の金属ハニカム体の製造方法に関する。
内燃機関付き自動車の排気ガス装置において排気ガスを触媒変換するために、触媒活性材料の担体として作用する金属ハニカム体が使用されている。そのような触媒担体の寿命並びに類似したハニカム体の他の用途における特性にとっては、ハニカム体を構成する個々の板金層が高品位のろう付け結合によって少なくとも一部の範囲が互いに結合されていることが重要である。そのようなハニカム体が耐熱耐食性鋼板から成り高温真空でろう付けされることが知られている。
このようなハニカム体は例えば西独特許出願公開第２３０２７４６号明細書あるいは同第２９２４５９２号明細書に記載されている。これらの明細書からハニカム体のろう付け法も知られている。
更に欧州特許第００４９４８９号明細書によって、ろうの付着量を少量にできる金属ハニカム体の接着・ろう付け法が知られている。更に西独特許出願公開第３８１８５１２号明細書にはそのような担体の接着・ろう付け法が記載されている。この明細書には公知のろう付け法の概説も含まれている。公知のろう付け法にはまた、欧州特許出願公開第０１３６５１４号明細書に記載されているようなろう粉末が表面力および機械的固着によって板金層に保持されるハニカム体の乾式ろう付け法もある。
更に国際公開第９３／２５３３９号パンフレットから、少なくとも構造化された板金層に圧延油の薄い層が製造工程で既に存在していなければ備えられるような金属ハニカム体の製造方法が知られている。続いて圧延油が熱処理され、これによって圧延油の揮発成分が除去される。そして圧延油の残留物が非常に薄い界面活性剤水溶液と接触させられ、これによって、乾燥による水分の除去後ろう粉末の付着に対する最良の条件を調えるような層が形成される。
本発明の課題は、経済的に実施可能なハニカム体の製造方法を提供することにある。またもう一つの課題はろう付け強度を向上することにある。
このような課題は、本発明によれば、少なくとも部分的に構造化された板金層を巻回して、積層してあるいは絡み合わせて構成され、一方の端面から他方の端面まで延びる通路を備えた金属ハニカム体を製造する方法において、
ａ）少なくとも構造化された板金層に圧延油層が板金層の製造工程時に備えられ、又きは板金層の製造工程後で次の工程ｂ）の前に備えられ、
ｂ）その後板金層から構成されたハニカム体がろう粉末と接触させられて、ろう粉末が圧延油に付着させられ、
ｃ）次いでハニカム体がろう付け処理されることによって解決される。
本発明の実施態様は次のように列記される。
・ハニカム体は好適には１００〜２００℃の温度に一時的に加熱され、加熱時間および加熱温度は、露出面上の圧延油の揮発成分のみが除去されるように選定される。
・ろう粉末はハニカム体の少なくとも一方の端面に付着させられる。ろう粉末はハニカム体の全長にわたって付着させられる。
・仕上げられたハニカム体が通路によって互いに接続される第１の端面と第２の端面とを有し、このハニカム体がろう付着処理され、その後ろう付け処理され、ろう付け工程中にハニカム体は横倒しに配置されて第１の端面および第２の端面が開放されている。
・板金層は少なくとも６０μｍ、特に少なくとも８０μｍ、好適には少なくとも１１０μｍの厚さを有している。
・少なくとも部分的に構造化された板金層は最大直径９０ｍｍ、好適には最大直径７０ｍｍのハニカム体（１）の形に巻回され、積層されあるいは絡み合わされている。
・ろう粉末は少なくとも４０μｍの粒径および６０μｍ以上、特に６３μｍの平均粒径を有している。
・ろう付け工程は真空中で行われる。
・ろう付け工程は保護ガス、特にアルゴンあるいは窒素のもとで行われる。
この本発明に基づく方法は、圧延油の完全な熱的および化学的処理並びに乾燥工程が省かれるので特に経済的に実施できる。驚くべきことに、ろう粉末が圧延油に直接付着している場合、ろう付け工程が向上したろう付け強度で実施できることが判明した。圧延油は好適には鉱性物質、脂肪物質および補助物質を含んだ市販の圧延油である。板金層を巻回してハニカム体を形成する際、板金層間に典型的な接触線が生じ、この接触線の近くに圧延油が毛管作用によって集められる。従って正にこの部分にろう粉末と接触する際に多量のろうが付着して残り、この場所は接続にとってもその多量のろうが必要とされる。
ろう付着の際に補助的にろうの分布に良好な影響を与えるために、ハニカム体の加熱によって部分的な熱的脱脂を行うことができる。その加熱温度および加熱時間は、揮発成分しか除去されず、特に接触線の近くになお十分な圧延油が残存するように選定しなければならない。これによってろう粉末と接触する際にハニカム体における露出面には僅かなろうしか残らず、接触線の部分には多量のろうが残り、これは正に好ましいことである。
圧延油は通常の周囲条件のもとでは乾かないので、ろう粉末が流出することなしにハニカム体を長時間にわたって搬送することも衝撃にさらすこともできる。
好適にはろう粉末はハニカム体の少なくとも端面側に付着させられる。ろう粉末の付着は、ハニカム体が渦流床におけるろう粉末の集積部の中に漬けられることによって行われる。渦流床へのハニカム体の浸漬深さに関係して、ハニカム体の軸方向におけるろうの付着長さが異なるようにすることができる。
他の実施態様、特に厚肉のハニカム体に対しては、ハニカム体はその全長にわたってろう粉末で被覆される。例えばニッケル基のろうが利用される。ろう粉末の平均直径は好適には６０μｍより大きく、ろう粉末は４０μｍの最小粒径を有している。
本発明の重要な観点は、ろう付け工程中にハニカム体が横に倒されて配置され横側端面が自由にされていることにもある。ろう付け工程中にハニカム体を横に倒して配置することによって、圧延油の粘性変化に基づいておよび温度が上昇して圧延油が蒸発する際にもろう材料がハニカム体から流出しないことが保証される。横に開いた端面を通しての真空引きおよび／又は保護ガスの供給は特に効果的に可能となる。
本発明の他の有利な実施態様によれば、板金層が少なくとも６０μｍ、特に少なくとも８０μｍ、好適には少なくとも１１０μｍの厚さを有していることが提案される。この板金層はハニカム体の公知の板金層よりも大きな厚さを有している。厚い板金層の場合、板金層とろうとの合金形成の影響は僅かである。好適には本発明に基づく方法は、最大直径９０ｍｍ、好適には最大直径７０ｍｍのハニカム体において実施され、これによって、ハニカム体を横に倒して配置してろう付けするろう付け工程中においてハニカム体の円形が変化しないことが保証される。この場合、ハニカム体を包囲するケース、特に外被管が通常の材料厚さを有していることから出発している。本発明に基づく方法を実施する際、高いろう摂取が達成される。この工程中に発生するろうのくずは比較的僅かである。高いろう摂取によって結合部における強いろう付けも行われ、これによって板金層の強固な結合が達成される。もっともこの方法は非常に薄い板金層およびろう粉末の非常に細かい粒度にも適用できる。
本発明によれば、少なくとも部分的に構造化された板金層を巻回して、積層してあるいは絡み合わせて構成され、一方の端面から他方の端面まで延びる通路を備えた金属ハニカム体を製造する方法において、
ａ）少なくとも構造化された板金層に圧延油層が板金層の製造工程時に備えられ、又は板金層の製造工程後で次の工程ｂ）の前に備えられ、
ｂ）その後板金層から構成されたハニカム体がろう粉末と接触させられて、ろう粉末が圧延油に付着させられ、
ｃ）次いでハニカム体がろう付け処理されることにより、ハニカム体を有利に製造することができる。そのようにして６０μｍ、特に少なくとも８０μｍ、好適には少なくとも１１０μｍの厚さを有する板金層を備えたハニカム体を特に有利に経済的に製造することができる。このようなハニカム体は特にオートバイ用の触媒担体として適している。
以下図面を参照して本発明に基づく方法とこの方法で製造された金属ハニカム体の特徴および利点を詳細に説明する。

図２はこのハニカム体の一部断面図である。

In order to catalytically convert exhaust gas in an exhaust gas apparatus of an automobile with an internal combustion engine, a metal honeycomb body that acts as a carrier for a catalytically active material is used. For such catalyst carrier life as well as characteristics in other applications of similar honeycomb bodies, the individual sheet metal layers constituting the honeycomb bodies are at least partially joined together by high-grade brazing. is important. It is known that such a honeycomb body is made of a heat-resistant and corrosion-resistant steel plate and is brazed at a high temperature vacuum.
Such a honeycomb body is described, for example, in West German Patent Publication No. 2302746 or No. 2924592. From these specifications, a method for brazing honeycomb bodies is also known.
Further, EP 00049489 discloses a method for bonding and brazing metal honeycomb bodies that can reduce the amount of brazing deposited. Furthermore German patent application in Publication No. 3818512 Adhesive brazing of such carriers are described. This specification also includes an overview of known brazing methods. Also Known brazing method, there is also a dry brazing of the honeycomb body to be held in the sheet metal layer by brazing powder surface forces and mechanical anchoring, such as described in EP 0136514 .
Furthermore, from WO 93/25339, a method of manufacturing a metal honeycomb body is known, in which at least a structured sheet metal layer is provided with a thin layer of rolling oil that does not already exist in the manufacturing process. Subsequently, the rolling oil is heat treated, thereby removing the volatile components of the rolling oil. The rolling oil residue is then contacted with a very thin aqueous surfactant solution, thereby forming a layer that adjusts the best conditions for wax powder adhesion after moisture removal by drying.
An object of the present invention is to provide a method for manufacturing a honeycomb body that can be carried out economically. Another problem is to improve the brazing strength.
Such a problem, according to the present invention, comprises a passage extending from one end face to the other end face by winding, laminating or intertwining at least partially structured sheet metal layers. In a method for manufacturing a metal honeycomb body,
a) At least the structured sheet metal layer is provided with a rolling oil layer during the production process of the sheet metal layer, or after the production process of the sheet metal layer and before the next step b) ,
b) then the honeycomb body is composed of a sheet metal layer is let contact with wax powder, wax powder was let adhere to the rolling oil,
c) then the honeycomb body is solved by being brazing.
Embodiments of the present invention are listed as follows .
The honeycomb body is preferably heated temporarily to a temperature of 100 to 200 ° C., and the heating time and heating temperature are selected such that only the volatile components of the rolling oil on the exposed surface are removed .
The brazing powder is adhered to at least one end face of the honeycomb body. The braze powder is deposited over the entire length of the honeycomb body .
The finished honeycomb body has a first end face and a second end face connected to each other by a passage, the honeycomb body being brazed and then brazed, and during the brazing process the honeycomb body The first end face and the second end face are opened side by side.
The sheet metal layer has a thickness of at least 60 μm, in particular at least 80 μm, preferably at least 110 μm ;
The at least partly structured sheet metal layer is wound, laminated or entangled in the form of a honeycomb body (1) with a maximum diameter of 90 mm, preferably a maximum diameter of 70 mm .
The wax powder has a particle size of at least 40 μm and an average particle size of 60 μm or more, in particular 63 μm .
-The brazing process is performed in a vacuum .
The brazing process is performed under a protective gas, especially argon or nitrogen .
This process according to the invention can be carried out particularly economically since the complete thermal and chemical treatment of the rolling oil and the drying step are omitted. Surprisingly, it has been found that when the brazing powder is directly attached to the rolling oil, the brazing process can be carried out with improved brazing strength. The rolling oil is preferably a commercially available rolling oil containing mineral substances, fatty substances and auxiliary substances. When a sheet metal layer is wound to form a honeycomb body, typical contact lines are generated between the sheet metal layers, and rolling oil is collected near the contact lines by capillary action. Therefore, a large amount of wax remains on the part when it comes into contact with the brazing powder, and this location also requires that large amount of wax for connection.
In order to have a good influence on the distribution of the brazing auxiliary during brazing, partial thermal degreasing can be carried out by heating the honeycomb body. The heating temperature and heating time must be selected so that only the volatile components are removed and in particular sufficient rolling oil remains near the contact lines. This leaves only a small amount of wax on the exposed surface of the honeycomb body in contact with the wax powder, and a large amount of wax remains in the contact line portion, which is exactly preferred.
Since the rolling oil does not dry under normal ambient conditions, the honeycomb body can be transported over a long period of time and subjected to impact without the wax powder flowing out.
Preferably, the wax powder is attached to at least the end face side of the honeycomb body. The attachment of the brazing powder is carried out by the honeycomb body being immersed in the accumulation portion of the brazing powder in the vortex bed. In relation to the immersion depth of the honeycomb body in the swirl bed, the adhesion length of the wax in the axial direction of the honeycomb body can be made different.
For other embodiments , particularly thick honeycomb bodies, the honeycomb body is coated with wax powder over its entire length. For example, nickel-based wax is used. The average diameter of the wax powder is preferably greater than 60 μm and the wax powder has a minimum particle size of 40 μm.
An important aspect of the present invention is that the honeycomb body is disposed sideways during the brazing process and the lateral end face is freed. Placing the honeycomb body sideways during the brazing process ensures that the brazing material does not flow out of the honeycomb body based on changes in the viscosity of the rolling oil and when the temperature rises and the rolling oil evaporates Is done. The evacuation and / or supply of protective gas through the laterally open end faces is particularly effective.
According to another advantageous embodiment of the present invention, the sheet metal layer is at least 60 [mu] m, it is proposed that in particular have a thickness of at least 80 [mu] m, preferably at least 110 [mu] m. This sheet metal layer has a larger thickness than the known sheet metal layer of the honeycomb body. In the case of a thick sheet metal layer, the influence of alloy formation between the sheet metal layer and the solder is slight. The method according to the invention is preferably carried out on a honeycomb body having a maximum diameter of 90 mm, preferably a maximum diameter of 70 mm, so that the honeycomb body is placed during brazing in which the honeycomb body is placed sideways and brazed. It is guaranteed that the circular shape of the will not change. In this case, the case surrounding the honeycomb body, particularly the outer tube, starts from having a normal material thickness. In carrying out the method according to the invention, a high wax intake is achieved. There is relatively little wax waste generated during this process. High brazing ingestion also results in strong brazing at the joint, thereby achieving a strong bond of the sheet metal layer. However, this method can also be applied to very thin sheet metal layers and very fine particle sizes of brazing powder.
According to the present invention, a metal honeycomb body having a passage formed from one end face to the other end face is manufactured by winding, laminating or intertwining at least partially structured sheet metal layers. In the method
a) At least the structured sheet metal layer is provided with a rolling oil layer during the manufacturing process of the sheet metal layer, or after the manufacturing process of the sheet metal layer and before the next step b) ,
b) then the honeycomb body is composed of a sheet metal layer is let contact with wax powder, wax powder was let adhere to the rolling oil,
By c) then the honeycomb body is brazed process, it can be advantageously produced a honeycomb body. In this way a honeycomb body with a sheet metal layer having a thickness of 60 μm, in particular at least 80 μm, preferably at least 110 μm, can be produced particularly advantageously and economically. Such a honeycomb body is particularly suitable as a catalyst carrier for motorcycles.
